Question

Mantoux test is done for the diagnosis of
A) Tuberculosis
B) Cholera
C) Malaria
D) Both B and C

Answer 1

It spreads from person to person through the air. When people with lung cough, sneeze, or spit, they propel the germs into the air. A person must inhale only a couple of those germs to become infected. About one-quarter of the world's population has been infected with these diseases, which means people have been infected by that bacteria but are not (yet) ill with the disease and cannot transmit it.

Complete answer:
The Mantoux test additionally called the tuberculin affectability test or Pirquet test. It is also termed as Mendel-Mantoux test. This test is used for the diagnosis of tuberculosis and is the main tuberculin skin test that is used around the world. It is used and endorsed by several states. In 1908 Felix Mendel, a German physician was the first to develop this test. It was first described in 1980 by Robert Koch.
Tuberculosis (TB) may be a contagious infection that sometimes attacks your lungs. It also can spread to other parts of your body, like your brain and spine. A type of pathogenic bacteria called tubercle bacillus causes it and its scientific name is Mycobacterium tuberculosis.

Additional information:
A dose of 5 units of tuberculin in 0.1 ml of solution is taken as a standard unit for the Mantoux test and is injected into the layers of the skin. It can be injected in between the wrist of the elbow, or on the left forearm. It will form a pale skin color where it is injected and is read after 48-96 hours but it is done better on the third day which is about after 72 hours. The person who is affected will show a certain immune response to the injection due to the presence of bacterial proteins. The person will show inflammation in the region where the injection was injected. The palpation and inflammation on the skin are measured in millimeters, if it is measured then the person is said to have tuberculosis and if the inflammation measured is at 0 mm then the person is said to be free from this disease.

So, the correct answer is ‘Tuberculosis’.

Note:
A TB disease doesn't generally mean you'll become ill. There are two forms of the disease:
Latent TB- You have germs in your body, but your immune system keeps them from spreading. You don't have any manifestations, and you're not infectious. Yet, the disease stays alive and may sooner or later become dynamic. In case you're in high danger for re-enactment - for example, in the event that you have HIV, you had a disease in the previous 2 years, your chest X-beam is strange, or your framework is debilitated - your primary care physician will offer you meds to stop dynamic TB.
Active TB- They make a person sick when their germs multiply. You can spread the disease to others. The vast majority of dynamic cases in grown-ups originate from idle TB contamination.
